usually in a single layer. Asci eight-spored. Spores cylindric, 
curved, greenish-hyaline or fuscous, 8-10 X 2 
Found recently on dead branches of Hevea hrasiliensis. 
The figure in Berlese, leones. III., plate CXV., is not typical. 
In general the stroma is fiat, with a single layer of perithecia, 
and pulvinate stroma which show distinct perithecia are rare. 
The ostiola, too, do not project as shown in the figure ; except 
with a high magnification they are not discernible. 
182.— Diatrype griseotecta B. & Br. 
Described by Berkeley and Broome as “ Peritheciis globosis 
immersis nigris, ostiolo papillæformi, e bysso griseo emer- 
gentibus.” They stated that the spores were 25 ^ long, 
scarcely mature. Cooke, in Grevillea, XIII., p. 58, stated 
that it was not a Diatrype, and that the spores were 
40 X 3 
The co-type in Herb. Peradeniya has scattered, superficial 
perithecia, black, subglobose below, conical above, with a 
fluted ostiolum. The perithecial wall is not carbonaceous, 
and is areola ted (by transmitted light). The substratum is 
covered by a thin layer of purple -brown hyphæ, which extends 
over the perithecia, leaving only the apices naked. The 
perithecia are “ immersed ” in this layer, not in the wood. 
The asci are cylindrico-clavate with a thickened apex, up to 
200 X 16 eight-spored, and the spores are cylindric, with 
rounded ends, about 60 x 4 pi. They are immature, but from 
the structure of the perithecium, and comparison with im- 
mature examples of Bombardia Janus (B. & Br.) Petch, this 
species is evidently an immature gathering of the latter. 
183. — Eriosphæria imitatrix (B. & Br.) Sacc. 
This species was described in Fungi of Ceylon, 1086, as 
“ SjpTiæria (Byssisedæ) imitatrix B. & Br. Lata effusa, e 
strato nigro oriunda ; peritheciis minutis collapsis asperulis ; 
sporidiis unisepta tis.” The spores were said to be oblong, 
subeymbiform, 15 ^ long. 
In the co-type in Herb. Peradeniya the perithecia are 
crowded together, seated on, or partly immersed in, a thin 
layer of purple-brown hyphæ. They are about 0*3 mm.
